Abstract
A plurality of first output terminals is provided along one side of a circuit element, and a plurality of input terminals and a plurality of second output terminals are provided adjacently along the other opposite side thereof. Leads include a first output lead extending from the first output terminal to an output connection electrode, and a second output lead extending from the second output terminal to the output connection electrode. The second output lead is extended from the other side of the circuit element to one side of the circuit element through a surface of a flexible wiring cable opposite the circuit element and further extended in parallel with the first output lead and connected to the output connection electrode.
